In order to more clearly and accurately explain the purpose, technical solutions and effects of the present disclosure, the present disclosure will be described in more detail below with reference to the accompanying drawings and examples. Note that the specific embodiments described herein are for interpreting the present disclosure and do not limit the disclosure.

Referring to FIG. 1, FIG. 1 is a flowchart of the RFID-based pill bottle smart control method of the present disclosure, and includes the following steps.

S10: Place a medicine bottle with an RFID electronic tag attached and capable of reflecting infrared rays into the medicine bottle storage rack. The medicine bottle storage stand is provided with a plurality of medicine bottle storage positions for storing medicine bottles.

In this embodiment, code information is stored in advance within the RFID electronic tag. The code information is the unique identification code of the RFID electronic tag. At the same time, the medicine bottle information corresponding to the medicine bottle is recorded in advance in the RFID electronic tag. For example, name, specifications, batch number, production date, expiration date, etc. The recording method is recorded with a portable RFID reading and recording device. Pre-recording of medicine bottle information within the RFID electronic tag can be completed in advance by the medicine bottle provider, or completed by medicine users, such as hospitals, when the medicine bottle is received. The outer surface or packaging of the medicine bottle must be able to reflect infrared rays. Black can absorb infrared rays, so do not use black on the outer surface or packaging of the medicine bottle.

S20: The mobile worktable equipped with an infrared sensor and an RFID reading and recording device is sequentially moved along the arrangement direction of the medicine bottles in the medicine bottle storage stand. Each time the mobile worktable moves to each vial storage location, the location of the vial storage location is detected and recorded on the vial storage stand.

Movement of the mobile worktable can be controlled by connecting to a control unit assembly. The control unit assembly may include a control host, a drive device, and a position detection device. The driving device can adopt a structure in which an electric part is added to the motor and a running wheel, etc., or a structure in which an electric part is added to the motor and a guide rail, etc. is added. The position detection device may be an encoder or the like. Of course, the driving device and the position detection device may be an integrated structure, such as a stepping motor or servo motor. In this way, the displacement of the mobile workbench is calculated by the control host and then the real-time position of the mobile workbench is obtained. Based on the real-time location, the mobile workbench can obtain which vial storage position of the vial storage unit and record that location.

For example, if there are multiple medicine bottle storage racks, the first number is J1, the second number is J2..., then the position number of the first medicine bottle storage location in the first medicine bottle storage rack is J1L1. The position number of the second vial storage position of the first vial holder is J1L2......The distance between J1L1 and J1L2 is 0.2m, and the cross section of the vial holder is used as the initial zero position, and the distance of J1L1 from the initial zero position is also It is 0.2m. After the vial storage unit moves, if the displacement amount fed back by the position detection device is 0.2m, 0.3m, 0.4m..., the control host determines that the mobile worktable is at the first vial storage position when the displacement is 0.2m. It can be judged as such and the current location can be recorded. If the control host determines that the displacement is 0.4 m, the mobile workbench is in the second vial storage position and records the current position. In this way, it can be inferred sequentially.

S30: Whenever the mobile workbench moves to each medicine bottle storage position, the infrared sensor detects the presence or absence of medicine bottles at the position according to the presence or absence of an infrared reflection signal. If there is a medicine bottle, the code information and medicine bottle information in the RFID electronic tag are read through an RFID reading and recording device, and the code information and medicine bottle information are bound in a corresponding relationship with the position of the medicine bottle storage location and stored in the database.

In one embodiment, whenever the mobile worktable reaches each vial storage position, if the displacement is 0.2m, 0.4m, 0.6m..., the infrared sensor of the mobile worktable sends infrared rays to the vial storage position. After emission, it is determined whether there is a medicine bottle in the medicine bottle storage location based on whether the infrared sensor receives the emitted infrared light. If there is a medicine bottle, the RFID reading and recording device of the mobile workbench is activated to read the RFID electronic tag of the medicine bottle, obtain the code information of the tag, the medicine bottle information, and the location information of the medicine bottle storage location, such as J1L2. It binds the corresponding code information and medicine bottle information in a corresponding relationship and stores it in the database, allowing workers to quickly look up the location.

In an embodiment of the present disclosure, the infrared sensor is a reflective infrared sensor. When an infrared reflection signal is received, it is determined that there is a medicine bottle at that location. If an infrared reflection signal is not received, it is determined that there is no medicine bottle at that location and the information about the absence of a medicine bottle at that location is stored in the database.

A reflective infrared sensor is equipped with a reflecting head or a receiving head. The reflective head emits infrared rays to the vial storage location of the vial holder. For example, if there is a medicine bottle in the medicine bottle storage location, the medicine bottle reflects the just-emitted infrared rays so that the receiving head of the reflective infrared sensor receives them, and the control host determines that there is a medicine bottle. The RFID reading and recording device is then activated to read information from the RFID electronic tag on the vial. If there is no medicine bottle in the medicine bottle storage location, the infrared light emitted from the infrared sensor is not reflected, and the receiving head of the infrared sensor cannot receive the infrared signal, so the control host determines that there is no medicine bottle. An embodiment of the present disclosure transmits information about the absence of a medicine bottle at the corresponding location to the database. In this way, through the location information of the medicine bottle storage unit, the worker can check whether there is an empty space in the medicine bottle storage unit and the specific location, making subsequent receipt and storage of the medicine bottles easy.

In one implementation method, the mobile work table according to an embodiment of the present disclosure stops moving each time it reaches each vial storage location, completes reading the vial information at that location, and then moves to the next vial storage location. The mobile workbench stops at each vial storage location to improve the detection accuracy of the infrared sensor and prevent missed vial detection.

In one implementation method, an embodiment of the present disclosure reads the code information and the vial information in the RFID electronic tag of the vial through an RFID reading and recording device in advance and stores the vial information in the database before putting the vial with the RFID electronic tag attached in the vial storage stand. . Through this, the medicine bottle information is first recorded, and then the location information is bound through detection of the movement of the mobile workbench, so that when a new medicine bottle is put in because there is an empty space in the medicine bottle storage rack, the medicine bottle information and location information are again provided for the storage location of each medicine bottle in each medicine bottle storage rack. There is no need to perform repeated binding, just bind the empty vial and location information.

S40: Repeat the previous steps until the mobile platform passes each vial storage location on the vial rack.

The RFID-based medicine bottle smart control method of the present disclosure binds the medicine bottle information of each medicine bottle storage position in the medicine bottle storage stand and the location information of the corresponding medicine bottle storage position through the movement of the mobile workbench and the infrared sensor and RFID reading and recording device of the mobile workbench. and save it in the database. Through this, medicine bottle information and location information can be automatically and quickly bound and recorded, and work efficiency is improved as there is no need to manually record location information one by one. In addition, when using the medicine bottle, the storage location of the medicine bottle can be quickly looked up through the database, so the worker can quickly extract the medicine bottle. At the same time, because the location and medicine bottle information are individually matched, the risk of medical accidents caused by incorrectly taking the medicine bottle can be prevented.

In addition, the pharmaceutical bottle smart positioning method combining infrared and RFID of the present disclosure can improve the storage efficiency of pharmaceutical bottles. For example, the RFID electronic tag of a medicine bottle is pre-worked by a medicine bottle supplier, and then when the hospital purchases and receives medicine bottles, the medicine bottle is first put into the medicine bottle storage rack, and then the location and medicine bottle information are bound using a mobile workbench. Miraculously, the medicine bottle information can be read into the database and stocking can be completed immediately.

In another embodiment, the RFID-based medicine bottle smart control method of the present disclosure may identify medicine bottles. This is as shown in Figure 2 and specifically includes the following steps.

S100 tag installation: Install an RFID electronic tag with an electronic code stored on the medicine bottle.

In this embodiment, the electronic code is a unique identification code of an RFID electronic tag. The RFID electronic tag can be attached to the bottom or side of the medicine bottle using double-sided tape or the like.

S200 Information input: Place the RFID reading recording device close to the vial and read the electronic code in the RFID electronic tag of the vial. If the electronic code does not exist in the database, the vial information of the medicine bottle is bound to the electronic code, entered into the database, and stored.

In this embodiment, information input refers to the manipulation of receiving a newly introduced medicine bottle. The reading recording function can be activated by placing the RFID reading recording device close to the medicine bottle and turning it on and off. After the RFID reading and recording device reads the electronic code in the RFID electronic tag, it first checks whether the corresponding electronic code exists in the database. If so, it is judged to be a new medicine bottle, and the medicine bottle information of the new medicine bottle, such as name, specifications, production date, etc., is bound to the corresponding electronic code and stored in the database to facilitate subsequent inquiry.

In one embodiment, the RFID read-write device can be manually moved closer to the vial or an automatically driven displacement mechanism can be installed to cause the RFID read-write device to move toward and closer to the vial.

S300 Vial Identification: Place an RFID reading recording device close to a vial and read the electronic code within the vial's RFID electronic tag. If the electronic code is present in the database, the medicine bottle information corresponding to the electronic code is retrieved from the database according to the electronic code and displayed.

In this embodiment, after the RFID reading and recording device reads the electronic code in the RFID electronic tag, when the electronic tag is searched in the database, it is determined to be a stock medicine bottle, and according to the electronic code, a medicine bottle corresponding to the electronic code is retrieved from the database. By recalling and displaying information, the identification process of the medicine bottle is completed, facilitating subsequent management tasks such as inventory survey and shipment.

Based on the intelligence of the medicine bottle identification process according to the method of the present disclosure, just by holding the RFID reading and recording device close to the medicine bottle, the RFID reading and recording device activates the reading and recording function to automatically and quickly complete identification, eliminating the need for manual comparison one by one. This eliminates the need for pharmaceutical bottle warehouse management, especially during the inventory taking process, which improves work efficiency. In addition, because the RFID electronic tag is adopted, even if the information on the medicine bottle is lost or deleted during the long-term storage process, the specific information of the medicine bottle can be accurately identified through the RFID electronic tag.

Because the RFID reading and recording device and the RFID electronic tag adopt RFID wireless communication, the RFID reading and recording device and the RFID electronic tag can be brought into contact within a certain distance, as long as the RFID reading and recording device can receive the signal emitted by the RFID electronic tag. There is no need to do this, and there is no need to align the two like with optical scanning of barcodes or QR codes. Therefore, the identification method of the present disclosure can perform mass identification of vials at a distance, and the identification process is simpler and simpler than contact or alignment operation.

In one implementation method, medicine bottle information is further stored in the RFID electronic tag according to this embodiment. When inputting information, when the RFID reading and recording device approaches the vial, the electronic code and vial information in the RFID electronic tag can be directly read and automatically entered into the database. In this way, the receipt record of medicine bottles can be completely automated. After automatically obtaining the electronic code upon receipt, the RFID reading recorder saves the electronic code and the medicine bottle information in the database to complete the record without the need to manually enter the medicine bottle information. do. Therefore, work efficiency when receiving medicine bottles is further improved. The medicine bottle information in the RFID electronic tag can be recorded in the RFID electronic tag in advance by the medicine bottle supplier through an RFID read-and-record device.

In one embodiment, the device of this embodiment further includes a display 600. The display 600 is connected to the control host 400. The database 500 is installed in the control host 400.

Specifically, the RFID reading and recording device 202 of this embodiment can be moved in the vial storage stand 100 to be closer to or farther away from the vial 700 in the vial storage stand 100. The RFID reading and recording device 202 and the RFID electronic tag 701 of the medicine bottle 700 are connected through wireless communication and obtain the electronic code in the RFID electronic tag 701. In this embodiment, the RFID reading and recording device 202 is installed on the mobile work platform 200. The mobile work table 200 moves automatically or manually along the medicine bottle storage table.

The control host 400 according to this embodiment receives electronic code information fed back from the RFID reading and recording device 202. Additionally, the electronic code is bound to the vial information of the vial and recorded in the database 500, or the vial information corresponding to the electronic code is retrieved from the database 500 and transmitted to the display 600 for display. When a medicine bottle is received, the electronic code in the RFID electronic tag 701 is bound to the medicine bottle information of the corresponding medicine bottle and entered into the database 500. When inventorying or distributing medicine bottles, the medicine bottle information corresponding to the electronic code is called from the database 500 according to the electronic code, transmitted to the display 600, and displayed to complete the identification process and subsequent inventory investigation and shipping operations.

In another embodiment, the RFID reading and recording device 202 is equipped with a Bluetooth module/WIFI module and connected to the control host 400 antenna. In this way, the RFID reading and recording device 202 can escape the connection constraints of the control host 400, and can move freely in the vial storage stand 100 very flexibly using the mobile work table 200, and the RFID of the vial 700 Identification of the medicine bottle 700 can be implemented by conveniently reading the information in the electronic tag.

Specifically, in one embodiment, the driving and position detection unit 300 according to this embodiment drives the mobile worktable 200 to move and detects the position parameters of the mobile worktable 200. Position parameters are parameters related to position calculation, such as displacement. The drive and position detection unit 300 includes a drive device and a position detection device. The driving device can adopt a structure in which an electric part is added to the motor and a running wheel, etc., or a structure in which an electric part is added to the motor and a guide rail, etc. is added.
